PLAYER-PIANO REROLL STOP.

Application filed June 23, 1924. Serial No. 721,775.

To allwltom it may concern.'

Be it known that I, ARTHUR TrNDLn, a citizen of the United States,residing at Nokomis, in the county of Montgomery and State of Illinois,have invented a new and Improved PlayenPiano Reroll Stop, of which thefollowing is a specification.

The invention relates to player pianos in which are included mechanismsair-actuated under control of a perforated music roll removablymountable upon the piano to be slowly unrolled to pass over the trackerbar for controlling the proper playing action and for being quicklyre-rolled for removal and replacement, and has for its general object toprovide automatically operating means for positively stopping there-rollinnr action, by engagement wlth the music roll itself forpreventing injurious flapping of the ends of that roll at theconsummation of the said re-rolling action.

In present practice, player pianos are commonly provided with a loweroperating roller and an upper removable roller readily mountable uponthe piano and carrying the perforated music roll selected to be played,the rollers being positioned below and above the tracker bar over whichthe music roll is slowly drawn from the upper roller to and upon thelower roller during the playing action and for the purpose ofcontrolling the playing of the piano automatically. lVhen the 'playingof the roll has been completed the reroll mechanisms arebrought intoaction and the upper roll is rotated, at relatively high speed, forquickly re-rolling the music sheet back upon the removable roll that thesame may be removed and replaced. The music rolls are each equipped witha securing hook whereby connection with the lower roller is made andwhen the re-roll action is consummated the high speed rotation of theupper roller continues freely for an interval of time during which thefree flap carrying the said securing loop flaps freely about the rolland in space in a manner for scarring thel piano and tearing the musicroll.

Therefore, it is an object of my present invention to provide anautomatically operating positive stop mechanism for engaging the musicroll at the consummation of the re-rolling thereof. just before thefinal turn` to thereby effectively prevent flapping or l-ahinz of the.free and the roll7 as ebow re 'fte It is a further object of theinvention to provide a simple and effective mechanism of the naturestated which is positive in its action and so cooperative with thetracker bar as to be air-actuatedat just such interval of time as willeffect stopping engagen ment with the roll at the very end of there-roll action and at a time when interference with or a wearing uponthe music notation perforations is impossible.

lVith the above and other objects in View, the invention still furtherresides in those novel details of construction, combination andarrangement of parts, all of which will be first fully described, thenbe particularly pointed out in the appended claims, and illustrated inthe accompanying drawings, in which Figure 1 is a diagrammatic frontelevation showing the application of the invention to the cooperativeparts of a player piano, the parts being about to function to effectstop action.

'Die take-up' ro'll 9 'is provided usual dutmut portionjlz and "the'sec' Q hook'13, which is b'cei i su? i F The ears 2O ofthe Supportingserve to accommodate t e 'main plvopin I upon which the main lever 22 oft e" lever mechanism is mounted. The said main lever 22 is pivoted at 23to a carrying head 24 which is slotted to provide upper and lower sidewalls, between the upper ones of which the pivot 23 is formed, andbetween the lower ones of which the pivots 25 of the stop strip carryingarms 26 are formed. The slotting of the carrying head 24 providesa'central web 27 which said web is extended and thread apertured toaccommodate the passage of a stop set screw 2S which is adapted toengage the abutment 29 formed on the outermost one of the carrying arms26 to adjustably limit the spread position of the said arms. The mainlever 22 is cut away, as at 30 to accommodate the head of the set screw28 when the lever device is positioned as illustrated in Figure 4, seeFigures 12 and 13.

The carrying arms 26 are each provided with a lug 31, and a fiat spring32 is positioned between the said arms in engagement with the said lugsfor the purpose of yieldably s reading the arms to the limit of theirsprea movement as controlled by the set screw 28. A stop strip 33 offelt or other suitable texible material is carried by the spread arms 26and the said strip is removably connected thereto through the medium ofthe metal securing clips 34, one of which is secured to each end of the.said strip and to the ends of the said arms in a removable manner, seeFigures 4, 12 and 13. It will be observed more particularly from Figure14 that the said clips 34 are bent from a sheet of spring metal to asubstantially S-shape, thus including a clamping jaw for clamping therespective strip end and another for clamping over the end of therespective carrying arm 26. It will also be observed from the saidfigures, that that portion of the clip which engages the said stripacutely is provided with tooth portions 35 that eiectively serve toprevent any tendency of slipping of the said strip when the lever deviceis applied, as indicated in Figure 4 of the drawings.

` 'lhe main lever 22 is extended and bifurcated as at 36 to facilitatethe pivotal connection 37 thereof with the pivot lever 38. The pivotlever 38 has the ends thereof pivoted at. 39 and 40 to the link arms 4l.between which the said lever is movable, and the centrally disposedlever arm 42 which is also pivoted at 43 to the projection 4t of thehead 24.

The main lever 22 is also extended and bifurcated at 45 to permitpassage of the centrally disposed level' arm 42 and to provide for thepivot connection 46 thereof with the operating arm 47 to which the linkarms 41 are also pivoted as at 48. The operating arm 47 is extendedrearwardly and has pivotedrthereto, as at 49. an actuating sleeve 50.

It will be observed by reference to Figures 3 and 4 of the drawings, andespecially to Figure 12, that the stop lever device, including all ofthe elements indicated by the reference numerals 19 to 50, is removableas a unit from the mounting therefor provided by the plate 17.

It will also be readily understood that, the `guides formed by thelingers 1S being friction guides, vertical movement of the slide 19 ofthe stop lever device will effect adjustment of position of the saiddevice, thus effecting the point and degree of contact of the saiddevice with the music roll.

Then the mechanism thus described is operatively mountedy in cooperativerelation with the piano parts in the manner illustrated in Figures 1 to-Lt of the drawings, the actuating sleeve i0 thereof is adapted toslidably engage the actuating rod 51, which is secured as at 52 to themovable board 53 of the bellows which forms a part of the pneumatic.Thus, when the -pneumatic is collapsed, in a manner soon to bedescribed, and the movable part 53 thereof moved from the position shownin Figure 3 of the drawings to that illustrated in Figure 4 of thedrawings, the actuating sleeve will be acted upon by the rod 51 andmoved to effect an application of the stop lever device, or rather thestop strip 33 thereof, to the music roll, as indicated in Figure 4 ofthe drawings.

The pneumatic includes the main or body portion and a head or capportion 56 which is removably mounted thereupon, suitable side arms orbrackets 57 being secured to the said head and provided with hangingflanges which are slotted, as at 58, to engage the hanging hooks 59carried by the rear face of the case wall 2 to provide a suitableremovable support for thc said pneumatic, see Figures tl and 4, andespeciallyV Figure 7.

A out oili valve 6() is secured to thc rear face of the case wall V2 ata point slightly above and behind the position of the music roll Thevalve 60 includes the rotary valve head 6l which is provided with asuitable valve passage adapted to open and close communication with thepassages 62 of the said valve. and an air duct 63 is ln'ovidcd forcommunieating one of the valve passages 62 with the tracker bar air portor aperture 7, Another air duct. provided for communicating theremaining air passage of the said valve with the atmospheric air chamber65 of the pneumatic head, through the rubber tube connection 66 and themetal tube section 67 leading into the said head chamber.

A, pouch 68 covers the chamber 65 between the head 56 and the body 55and a lateral chamber 69 communicates, through the bleeding vent 70,with the pneumatic exstop lever device will be actuated to immediatelybring the stop strip 33 thereof down into contact with the music stripin a manner for preventing a sin le additional complete rotation of themusic roll, theieby effectively preventing all tendency of lashing ofthe end of the music strip. It will be observed that the link connection42 of the stop lever device is so pivotally related to the main lever 22as to be in the nature of a parallel lever and such as will effectmovement of the levers in cooperation for `maintaining the carrying head24 in a substantially like position during the whole of the range ofmovement of the said stop lever device, see Figures 3, 4 and '12, thusensuring proper en agement of the stop strip 33 with the music rollstrip.

The stop lever device having thus been applied and served its functionin preventing lashing of the free end of the music roll strip, theoperator, seeking to remove and replace the played music roll, willreach forward and grasp the same, simultaneously touching the lever 86and moving the valve to the closed position. This free movement of thevalve independently of the lever, link and crank devices 88 to 92inclusive, being permitted by the slot of the link 88, and therebyclosing ofl' passage of atmospheric air and permitting the pneumatic toautomatically adjust itself to the normal infiated position, therebyeffects an instantaneous operation of the stop lever device such as willelevate the same to the normal position illustrated in Figures 3 and l2of the drawings. Then, of course, when the re-rolled lever 11 is movedover to the right, see Figure 8 of the drawings, to thus set the powertransmission devices for effecting a playing of the new music roll nowapplied to the piano, the lever, link and crank devices 88 to 92inclusive will be automatically acted upon, simultaneously with thesetting of the power transmission devices, to efi'ect an opening of thevalve 60, such as will permit free paage through the passages 62thereof, so that when the port 7 is again uncovered at the end of there-rolliiig action, the stop lever devices will be again automaticallybrought into action in the manner hereinbefore described.

It is a particular feature of the iiivention to position the air port 7adjacent the right end of the tracker bar beyond the music perforationsthereof. Thus, there will be no music perforations on the music strip inposition for passing over the said air port. lt is desirous that the airport be so positioned that only blank paper will pass over the same forif there were any perforations in the music roll positioned for passingover the said port the stop lever device would be automatically broughtdown into engagement with the music Strip during the playing thereofwhich, of course, is not desired. As now constructed, as the taperedfiap of the music roll uncovers the said port at the end of the re-rollaction, the stop lever device is applied in a manner for preventing asingle additional whole rotation of the music roll, thus effectivelypreventing all tendency to lash of the free end of the strip, and thisaction is so automatically effective in coopeiation with that portion ofthe exhausting apparatus with which the devices are cooperativelyconnected that after the said stop lever has' thus been automaticallyapplied, the harder one pumps the tieadles of the piano, thc firmer willthe said stop lever be applied to the music strip until the said cutoffvalve is finger-actuated by the lever 86, as above described.

It is also a particular feature, in addition to the. main feature ofproviding an automatically actuated stop lever device, to provide thefinger closing means for the valve and also the link, lever and crankdevices automatically actuated in eoopeiation with the re-roll lever.Obviously after the valve has been closed by the finger engaged lever 86it is necessary that the saine be returned to the open position so thatthe mechanism may automatically function again at the end of the re-rollaction. lf the crank, lever and link devices were not provided, it wouldbe possible for the operator to forget to reset the valve to the openposition and the device would not function; but by providing thesedevices, the said valve is automatically reset when the operator' setsthe re-roll lever to the playing position which, of course, is necessaryto effect a playing of the replaced roll.

The provision of the balance wheel is also a feature as it will ensureeasy and steady rc-rolling and will prevent the music strip frombouncing during the re-rolling action and thus exposing the air port 7which automatically controls the application of the stop lever device.This inadvertent exposing of the air port by the bouncing of the musicstrip would cause considerable trouble as the stop lever device would beautomatically actuated before the re-rolling action was completeddepending on what point during that action the uncovering of the portoccurred. The provision of this balance wheel effectively serves toprevent all possibility of trouble, as before stated.

In Figure l5 of the drawings is illustrated a modified lever connectionbetween the reroll lever and the cutoff valve lever for operating thelatter in cooperation with the former. In this modification, the re-rolllever 11 has the saine crank portion 91 at the rear end thereof. Thecrank 91 is linked at 93 to the crank lever 94 which is in turn llt) llink connected as at 95 to the rocking levers mimic strip jconnectedlwith the; sheet having a up@ It is preferred that the stop lever devicesconstructed of metal, such as brass nickel, 'silver or aluminum to matchthe trlmmin of the piano upon which itl is mounte This, of course, 1s otional to the manufacturer and l do not wlsh to be limited to such use.
